Command Palette: Add keywords to admin menu commands

[jdeep]

The Command Palette registers a command for every admin menu item (#63845), but these commands can only be found by their label. Searching for "favicon", "timezone" or "password" finds nothing, even though Settings > General and Users > Profile are where those are.

The Command Palette has supported keywords since ​Gutenberg #70624. When ​Gutenberg #71476 moved admin navigation to commands generated from the admin menu, there was no longer a way to attach keywords to them. That was listed as one of its trade-offs.

The proposal is that keywords come from PHP, next to the label, url and name that wp_enqueue_command_palette_assets() already sends.

Proposed change

• A new function, wp_get_admin_menu_command_keywords(), returns keywords for core admin screens, keyed by menu slug.
• A new filter, admin_menu_command_keywords, lets plugins add keywords for their own pages. They key them by the same $menu_slug they pass to add_menu_page() or add_submenu_page().
• wp_enqueue_command_palette_assets() adds a keywords list to each top-level and submenu command. Commands without keywords get an empty list.

For example, a plugin could add:

add_filter(
        'admin_menu_command_keywords',
        function ( $keywords ) {
                $keywords['my-shop'] = array( 'orders', 'products' );
                return $keywords;
        }
);

The Gutenberg side, which passes the keywords through to the palette, is in ​Gutenberg #84834.

Adds keywords to the admin menu commands in the Command Palette, so admin screens can be found by words that are not in their label. For example, "favicon" finds Settings > General and "password" finds Users > Profile.

• New wp_get_admin_menu_command_keywords() returns keywords for core admin screens, keyed by menu slug. Each keyword is translatable with the command palette keyword context.
• New admin_menu_command_keywords filter lets plugins add keywords for their own pages, keyed by the $menu_slug they pass to add_menu_page() or add_submenu_page().
• wp_enqueue_command_palette_assets() adds a keywords list to each top-level and submenu command. Commands without keywords get an empty list.
• New tests in tests/phpunit/tests/dependencies/wpEnqueueCommandPaletteAssets.php.

The palette uses these keywords once WordPress/gutenberg#84834 is in core. Until then, the keywords are sent but ignored.
